Glaucium sp.? Kew

Leaves very hairy, but also bloom for instantly wetted after being touched with ether. Then numerous long hairs are coated with bloom which is instantly removed by Ether. Drops of water falling on leaf are instantly shot off.

Waving for 1' in water at 91° did not remove silver, but for additional 1' in w. at 95° did do so; yet the hairs were not rendered nearly so transparent as by Ether. Sponging for short time with water at 90° well wetted the leaf. —

Aug 18th 8° 45' cleaned 8 spaces with sponge & water at 90°. & put on salt & f. w. on 4 of each. 2 leaves leaf pinned down; put spheres of salt water on each leaf. —

Aug 21st 3 salt-patches brown, 22d still browner}

22d spheres on mid-rib very slight discolouration}

23d The 4th spots with salt brown

Perhaps a little discoloration from fresh water}

24th certainly some discoloration from fresh water} Frank

26th Where salt-water lay now utterly rotten.

remarkable effect (over)

[85v]

Aug 26' the 2 spheres of salt have caused no injury, though a point close by one sphere has from some cause become rotten. —

I can see no injury from fresh water.

(Aug. 30th. The rotting on all 4 places where salt lay has now spread far beyond where drops lay. — where spheres lay surface slightly yellowed, but this has appeared very lately. —

Where fresh-water lay no effect in 2 places, in 2 other places surface slightly browned, but then the whole leaf has begun to decay & the result doubtful.)

Aug. 26th Compared hairs on leaf to which nothing had been done & a bit waved for a few seconds in S. Ether & in turpentine + [illeg], & the hairs presented a conspicuous difference — The fresh hairs so much coated with white matter that the partitions of multicellular hairs difficult to see, whereas quite clear in the other 2 specimens.—
